Definitions

  • This invention relates to apparatus for assembling an elec ⁇ trical connector to an end portion of a multiconductor electrical cable having a cable sheath .
  • apparatus of this kind comprising a table which is movable in opposite directions along two mutually perpendicular paths relative to a cable clamp assembly , the table carrying a cable stripper assembly and a connector applicator assembly with means for feeding connectors to the applicator assembly.
  • the table Is arranged to be moved cyclically in such a way that first a cable held by the cable clamp assembly has the sheath stripped from an end portion thereof by the cable stripper assembly , whereafter the leading connector of the strip is held in the applicator assembly and is moved onto the stripped end of the cable and is applied thereto by the applicator assembly .
  • the distance that these assemblies are moved towards and away from the clamp assembly is determined by the distance of travel of the table towards and away from the clamp assembly .
  • the movement of the stripper assembly and the applicator assembly relative to the clamping assembly cannot be individually controlled and especially the depth of insertion of the stripped cable end into the connector .
  • other operations are to be carried out on the stripped cable end, for example, if the cable has a shield which is to be folded back against the cable sheath so that it does not enter the connector , the travel of means for effecting this operation , which may be provided on both the stripper and the applicator assemblies needs to be closely controlled.
  • the invention is intended to provide apparatus for as ⁇ sembling an electrical connector to a end of a multiconductor electrical cable having a cable sheath , which apparatus is sus- ceptible to more accurate control than the apparatus referred to above and which is also more versatile in that it can be provided with means for processing a metal shield made, for example, of metal foil , when such is present between the cable jacket and the cable sheath .
  • the table is arranged to be translated only along a first path extending past the cable clamp assembly, means being provided for translating the stripper and applicator assemblies in two opposite directions and independently of one another , along respective second paths on the table, which paths are perpendicular to the first path , drive means for said assem ⁇ blies and the connector feeding means being so controlled , by means of a control unit, that the end portion of a cable held by the clamp assembly is stripped of the sheath by the stripper assembly , a connector fed to the applicator assembly by the feeding means is moved onto the stripped end portion of the cable and the applicator assembly is actuated to apply the con ⁇ nector fed thereto to the stripped end portion of the cable * .
  • the stripper assembly may be provided with a pair of rotary cutting rolls for slitting opposite sides of the shield when the sheath has been stripped from the cable end , to divide the shield into a pair of flaps at the cable end .
  • the flaps may be opened to a prede ⁇ termined extent, by means of a blower device on the table , and the flaps may be folded back against the cable sheath by means of the applicator assembly, for example , by means of a pair of brushes , preferably wire brushes , which are movable under the action of the control unit between a closed shield folding back position and an open position to allow the cable end subsequently to be passed between the brushes into the connector that has been fed to the applicator assembly.
  • a pair of brushes preferably wire brushes
  • a tool for opening out the metal shield of a shielded cable, by means of a blower device and for subsequently folding the shield back against the sheath of the cable is described in US-A-3 ,621 ,560 but the cable shield is not, however , slit prior to these operations and the folding back operation is not per ⁇ formed by means of brushes .
  • US-A-3 ,316 ,781 means for slitting the insulation of a cable by the use of rotary cutting rolls .
  • Wire end processing apparatus employing relatively movable wire clamping , wire cutting , and connector applying , means are disclosed in US-A-4 ,377 , 898.
  • the clamp assembly preferably comprises a cable clamp which can be moved between a partially open position to allow the cable end portion to be inserted through the clamp, a closed position to grip the cable , and a fully open position to allow ejecting means of the clamp assembly to eject the cable from the clamp after the connector has been applied to the stripped cable end portion .
  • the movements of the parts mentioned above, are coordinat ⁇ ed by means of the control unit and are preferably closely monitored by means of sensors . These sensors may be arranged to immobolize the apparatus in the case of malfunction and pre ⁇ ferably also to cause the control unit to display an indication of the fault.

Abstract

Le dispositif comprend un plateau (156) et est mobile le long d'un premier chemin au-delà d'un organe fixe de serrage de câble (40), le plateau (156) portant un assemblage de dénudage de câble (42) et un assemblage applicateur de connecteur (44) qui sont mobiles indépendamment sur le plateau (156) le long de cheminements perpendiculaires au deuxième cheminement. Le plateau (156) et les deux assemblages (42 et 44) sont disposés de manière à se déplacer cycliquement afin de permettre d'abord le dénudage par l'assemblage (42) d'une extrémité terminale d'un câble (28) maintenu par l'organe de serrage de câble (40), après quoi un connecteur (2') amené au préalable jusqu'à l'assemblage applicateur (44) est appliqué sur l'extrémité du câble (28). L'assemblage de dénudage (42) peut présenter un organe de fendage (70) de l'isolation du câble et l'assemblage applicateur (44) peut être pourvu d'un organe (74) servant à replier vers l'arrière ladite isolation.
